Tatted medallion in progress

Well... tatting in progress :)  I have forgotten how much I enjoy tatting this little motif 

Please take  a look at this comparison of different thread sizes.

The black motif is in size 5 (Aida I believe), beige motif is size 10 (Lizbeth I suppose ) and blue one is size 20 (Lizbeth again)

If you would like to try this yourself here is the pattern
